Abstract

Des modes de réalisation de l'invention décrivent un circuit dans lequel un circuit de modulation fournit un premier signal électrique modulé et un deuxième signal électrique modulé, et un signal électrique modulé donné, qui peut être soit le premier signal électrique modulé soit le deuxième signal électrique modulé, comprend des données modulées par déplacement minimal (MSK). De plus, un premier élément d'ajustement de phase, qui est couplé au circuit de modulation, règle une phase relative entre le premier signal électrique modulé et le deuxième signal électrique modulé en fonction d'une valeur de phase du premier élément d'ajustement de phase. De plus, une interface de sortie, qui est couplée au premier élément d'ajustement de phase, est couplée à un ou plusieurs éléments d'antenne qui émettent des signaux. Ces signaux comprennent un signal modulé par quadrature de phase (QPSK) correspondant au premier signal électrique modulé et au deuxième signal électrique modulé.
